Visual Cue: Point to Self: Examiner points to body parts on himself, and subjects are required to point to the homologous part on themselves. D: Visual Cue: Point to Examiner: Examiner points to a body part on the subjects, and they are required to point to the homologous part on the examiner. E: Blindfold Post-Visual Cue: Point to Self
Two major cue types are used to analyze attention based on the type of visual input. An endogenous cue is presented in the center of the screen, usually at the same place as the center of focus. It is an arrow or other directional cue pointing to the left or right box on the screen. This cue relies on input from the central visual field.
The cue recruitment experiment is a form of classical conditioning experiment, the simplest test for associative learning in which one (or at most a few) new signal(s) are put into correlation with one or a few trusted cues. Cue recruitment (a change in perceptual appearance) does not always occur during a cue recruitment experiment.
Astereognosis (or tactile agnosia if only one hand is affected) is the inability to identify an object by active touch of the hands without other sensory input, such as visual or sensory information. An individual with astereognosis is unable to identify objects by handling them, despite intact elementary tactile, proprioceptive, and thermal ...
Direct Visual Feedback is a method of training used in both practical and rehabilitative settings where the attention of the trainee is tied to an external visual cue in reference to the particular movement, motor function or exercise that is being performed by the trainee. The principle to Bio-Feedback is very similar to DVF.
Cued speech is a visual system of communication used with and among deaf or hard-of-hearing people. It is a phonemic-based system which makes traditionally spoken languages accessible by using a small number of handshapes, known as cues (representing consonants), in different locations near the mouth (representing vowels) to convey spoken language in a visual format.
The mirror box gives visual feedback that can allow a person using it the opportunity to "see" the missing hand, and to manipulate the hand in an attempt to relieve pain or discomfort. Virtual reality is also used to treat phantom limb pain in a similar way, by allowing the user to "see" the missing limb within the virtual world and manipulate ...
The visual system can detect motion both using a simple mechanism based on information from multiple clusters of neurons as well as by aggregate through by integrating multiple cues including contrast, form, and texture. One major source of visual information when determining self-motion is optic flow. Optic flow not only indicates whether an ...
